SADDLE-CANTI@ MACHINE.

Application filed September 2'7, 1916.

To all whom t may concern.'

Be it known that I, "WILLiAu S. OvnRmN,

a citizen of the United States, residing in and State of Oregon, have inventedy certain new and useful Improvements in Saddle- Cantle Machines, of which the following is a specification.

My invention relates to saddle cantle machines,and.more particularly to a machine for automatically and mechanically finishing cantle forms for saddles. These cantles are of oval, dish-like form, convexed on one side and concaved on the other, with a segment cut out of one side thereof. Heretofore it has been necessary to form, or finish, these saddle cantles by hand. The object of my invention is to provide a machine by means of which one or more saddle cantles can be automatically formed, or finished,

and according to a pattern secured on the' machine and the form of which is duplicated Vin the cantles during the operation of the machine.

In order that others may understand my invention I have illustrated one practical embodiment thereof on the accompanying two sheets of drawings, which Iwill now describe.

Figure 1 is a front elevation thereof;

F ig. 2 is a top plan view thereof;

Fig. 3 is an end view thereof, as seen from the right hand end of Fig. 1;

Fig. 4 is a top plan view of a pilot, or guide, which travels upon the pattern;

Fig. 5 is a top plan view of a finished saddle cantle form, such as my invention is designed to form; and

F ig. 6 is a cross sectional view thereof, on line 6 6, of Fig. 5.

4Referring now more in detail to the drawings, 1 designates a box-like table structure having a table top 2, supported upon legs 3 3 and 4 4. The legs 3 3, may be eX- tended above the-table top 2, at one end thereof, as at 3a 3, and provided at their upper ends with a cross piece 5. Movably mounted upon a pair of guide members 6 6, upon the table top 2, is a supporting and carrying block 7, upon which is mount ed a pair of bearing standards 8 8, carrying the shafts 9 land 10, shaft 9 being provided with a belt pulley 9, and the shaft `10 being provided with. a similar belt pulley l0, over which run belts 1l and l2, respece Specification of Letters Patent.

tively, which belts extend through the table top 2, to a common pulley 13, by which said belts are driven, and on whichthey travel as said block 7, and said standards 8 8, are moved upon the guide members 6 6, in a manner now to be described.

The pulley 13, is mounted upon a driving. shaft 14, the opposite ends of which are supported in bearing standards `15 15, said shaft being provided near its outer end with a driving pulley 16, as shown. Mounted in bearings 1-7 17, on the under side of the' box-like structure is a shaft 18, on which is mounted a large pulley 19, which is driven by a belt 20, from a small pulley 2l, on the shaft 14. @n the outer end of said shaft 18, is a pulley 22. A short cross shaft `23, is mounted in bearings 24 24, and is provided with two pulleys 25 25, `over which run a belt 26, from the pulley 22, lsaid belt extending to and around a pulley 27, mounted upon a vertical shaft 28, having a bearing at its lower end, at 29, and extending upwardly through the table top 2, with a bearing 30 mounted thereon, said shaft 28, being pro vided at its upper end with a pulley 31.

Also mounted on the outer end of the shaft'18, is a small pulley 32, upon which runs a belt 33, extended upwardly over a circular saws 37 and 38, which are driven by the belts 11 and 12, from the large pulleyV 13. Also mounted in bearings at the lower ends of the standards 8 8, upon said supporting and carrying block 7, isa shaft 89, shown in large view in Fig. 4, and provided at its operating end fwith an" L, or oif-set 39, adapted to receive a bearing bolt `stud 40, secured thereto by means of a nut 41, and upon which is mounted a pilot ldisk 42,: having a cylindricahor body', portion 143, within which is a roller bearing mechanism, clearly indicated in dottedlines inV Fig. 4, whereby said pilot `disk` 42, is made to run easily and accurately. In order to rotatably adjust said shaft 39, it is provided with an one directly above the other, and that the Y pilot disk is mounted directly underneath the saw 38. and 38, and the pilot disk 42, are in alinement with each other and at fixed spaces apart.

Mounted upon the table top 2, in a suit-A able bearing 47, is a vertical shaft 48, the upper end of'which is held in proper positionby means of a bracket 49,hinged to the cross piece 5, as at 50--50, said bracket 49., being detach'ably'` secured to the upper end of said shaft 48, by meansof a thumb nut 51, whereby, when said thumbnut is removed, said bracket 49,'can be raised into a vertical position, as indicated by the curved dotted line, Fig. 1. Detachably mounted on said shaft 48, is a sleeve 52,

Vhaving secured thereto one or more work tables, as 53 and 54, and a pattern table 55, on which a pattern 56, is mounted. Secured to saidsleeve underneath said pattern table 55, is a pulley 57. A belt 58, fromV the pulley 31, on the upper end of the vertical. shaft 28,V is extended around said pulley 57, for driving said sleeve 52, and the pattern and work tables secured thereto. The vertical shaft 48, has a hole 59, bored into its upper end a short distance, and out to the'side, as indicated in dotted lines, Fig. 1, through which oil is fed from a drip spout 60, connected with an oil' reservoir 61, providing a sight feed of oil through the hole 59, and down through the sleeve 52, to the bearing upon which the sleeve turns at its lower end. Said sleeve at its lower end rests and turns upon a ballrbearing collar'62, seated upon a bearing ring 63, having an annularV groove in its edge into the opposite sides of which fit inwardly projecting fingers 64-64, in the outer end of a pivoted frame 65, secured to the shaft 66, as clearly shown in Figs. 1 and 2.

Secured to Vsaid shaft 66, is a lever 67 having connected to its upper end a connecting rod or link 68, the opposite end of which is connected to a hand lever 69, pivoted to the 'standard 3a, Vas clearly seen in Figs. 1 and 3. kA spring 70, is attached at one /end to the lever 67, and atits opposite end to an eye 71, in the table top 2, as` shown, said spring operating to draw the lever 67, backwardly, thus rocking the shaft 66, and yieldingly raising theframe 65, and the sleeves 52, together with the pattern and Awork tables carried thereby. When it is desired to move said pattern and work, tables downin other words, the saws 37 wardly to their lowermost position, and against the tension of the spring 70, the hand lever 69, is drawn down to theposition shown in dotted lines.

A spring 72,`is attached, as at 73, to the supporting and carrying block 7 and at its opposite end to the upright standard 3 for the lpurpose of holding the supporting and carrying block 7, firmly as it is moved by the screw-shaft 35. Y

ln Figs. 5 and 6, I have shown plan and sectional views of a saddle cantle form, such as my invention is 'designed to finish. These cantle forms are prepared in the rough by hand, and up tothe present time have been` finished by hand. That is, the convexed surface has been formed by hand work, as has also the concaved, or inner, surface. my invention, however, this conveXed surface, and also the concavedsurface, can be more uniformly and rapidly made by machinery. Y

While 1 have *shown only the pattern table with a pattern for forming the finished convened surfaceof the cantle, it will be evident that4 the principle of my invention can be applied in forming the finished concaved surface of the cantle, and I' prefer to do this by removing the sleeve 52, together with the pattern and work tables from the shaft 58,

vided with work tables and a pattern table,

with a concaved pattern, secured thereto, i

but as my invention is fully and clearly illustrated in the present showing itis not necessary to show other forms.

The use and operation'of my invention may be briefly described as follows:

Assuming that the pattern for the convexed surface is in place on the pattern table 55, and that the saddle cantle formsin the rough are secured tothe work tables 53 and 54, so as to turn therewith, the supporting and carrying block7, is moved to its innermost. position toward the work tablesv so that the saws are directly above the central portion of the pattern 56, it'being understood that the sleeve 52, with the work tables and pattern table are depressed to their lowermost position against thetension of the spring 70, and are held ,down by the engagement of the pilot disk'42, with the top surface of the pattern 56, which is preferably of iron. As the machine is driven the saws, of course, are revolving and the sleeve 52 with the tables thereon are also revolving, the saws 37 and 38 cutting away the portions of the rough forms onthe work table as they revolve, the pilot disk 42, following the form of the pattern 56,.and causing the pattern and pattern table together with the work tables to be depressed spring asthe surface of the pattern requires,

thus causing the saws to act upon and form the work to correspond with the surface of the pattern, as indicated in F ig. l. During the operation of the machine the supporting and carrying block 7, is being gradually moved away from the sleeve 52, thus moving the saws gradually outwardly toward the outer edges of the work tables and the pilot disk 42, gradually outwardly toward the outer edge, or rim, of the pattern 56.

Thus it will be seen that, broadly considered, my invention comprises a pattern table,^or support, with one or more work tables, all revolubly mounted to be turned together, with means for moving them bodily longitudinally of the axis of rotation, together with a pilot member revolubly mounted and operating on the pattern, with one or more cutter members operating in connection therewith, adjacent the work tables, said pilot member and cutter members being driven together and being movable bodily as a unit longitudinally of their axis of rotation. The pilot member and the cutter members revolve about the axis at right angles to the angles of rotation of the pattern and work tables.

While I have illustrated the preferred embodiment of my invention, I am aware that many changes can be made therein, without departing .from the spirit thereof, and I do i not, therefore, limit the invention to the form here shown, except as I may be limited by the hereto appended claims.

I claim:

l. In a machine of the character referred to, in combination, a pattern table and one or more work tables revolubly mounted one above the other at a space apart to turn as a unit about a common axis, means for turning the same, means for raising and lowering the same, a supporting member movably mounted, with means for moving the same horizontally `toward and from said tables, a pilot member and one or more cutter mem* bers revolubly mounted onsaid supporting member and projecting, respectively, over said pattern table and said work tables, means for driving the cutter members, and operating driving connections, whereby said pattern and work tables and said cutter members are driven together, and said supporting member is moved bodily to carry said pilot and cutter members cross-wise of said pattern and work tables, substantially as described.

2. In a machine of the character described, the combination of a rotatable element mounted to shift and carrying means for supporting thereon a pattern and work at different positions along said element, a pattern follower and a rotary cutter for engaging the pattern and work, respectively, said pattern follower and cutter and said element being relatively movable in a path at an angle to that in which said element is shiftable, and means for yieldingly forcing said element longitudinally of its axis in a direction for forcing the pattern and work into engagement, respectively, with said follower and cutter.

8. In a machine of the character described, the combination of a rotatable element mounted to shift and carrying means for supporting thereon a pattern and work at different positions along said element, a pattern follower and a rotary cutter for engaging the pattern and work, respectively, said follower and cutter being movable in a path at an angle to that in which said element is shiftable, and means for yieldingly forcing said element longitudinally of its axis in a direction for forcing the pattern and work into engagement, respectively, with said follower and cutter.
